title: Structural characterisation and absolute stereochemistry of some degraded carotenoids from New Zealand honeys

authors: Broom, Susan J.

abstract: The structures and absolute stereochemistries of some degraded carotenoids from New Zealand native honeys were elucidated. 

Determination of the absolute stereochemistry of 3,5,6-trihydroxy-β-ionone was attempted by an enantioselective synthesis. A racemic synthesis was achieved starting from β-ionone. The key steps involved regioselective hydroboration of 3,4-dehydro-β-ionone, followed by molybdenum-mediated stereoselective epoxidation of the resulting homoallylic alcohol. Ring opening of the epoxide afforded the required trihydroxy-ionone. Synthesis of both enantiomers of 3,5,6-trihydroxy-β-ionone via enantio- and regioselective functionalisation of 3,4-dehydro-β-ionone was not achieved. Methods of enantioselective enzyme-mediated kinetic resolution of cyclic homoallylic alcohols were investigated. A satisfactory procedure was not developed. 

The absolute stereochemistry of 3,5,6-trihydroxy-β-ionone was determined by analysis of the diastereoisomeric proton chemical shifts of (S)- and (R)-α-methoxyphenylacetate (MPA) derivatives using the extended Mosher-Trost configurational model. This analysis indicated a 3S,5R,6R absolute configuration, the same configuration as 3,5,6-trihydroxy carotenoids. The natural product was extracted from thyme (Thymus vulgaris) honey using established procedures.

Diethyl ether extracts of kamahi (Weinmannia racemosa) honey were found to contain three diastereoisomers (kamahines) of an unusual degraded carotenoid with a 14 carbon skeleton. After acetylation, one of the isomers was fully characterised by multidimensional ¹H and ¹³C NMR spectroscopy, and single-crystal X-ray crystallography, indicating the parent alcohol was 4,5-dihydro-1',5-dihydroxy-2',4,8',8'-tetramethylspiro[furan-2(3)H,7'[6']oxabicylco[3.2.1]oct[2']ene]-4'-one. Comparison of NMR-derived NOE and coupling constant data of kamahine A and B acetates with kamahine C acetate indicated the parent kamahines were C-4, C-5 epimers.
 
The absolute configurations of the kamahines were determined by NMR and a molecular modeling study (MacroModel) of the diastereoisomeric hemiacetal MPA esters. The results of the determination, coupled with a consideration of crystallographically-determined hemiacetal ester conformations obtained from a search of the Cambridge Structural Database, supported the use of the Mosher-Trost model for determination of the absolute configurations of hemiacetals. Furthermore, this analysis suggested that the Mosher-Trost model should be amended to take into account a torsion angle of +25-50° between the methine proton and the carbonyl of hemiacetal MPA esters. Kamahines A-C were shown to have the absolute configurations 1'R,2R,4R,5S,5'S, 1'R,2R,4S,5S,5'S and 1'R,2R,4R,5R,5'S, respectively. The absolute configurations of kamahines A-C were consistent with an abscisic acid precursor.

title: Enacted stigma, mental health, and protective factors among transgender youth in Canada

authors: Veale, Jaimie

subjects: adolescence

abstract: Purpose: We aimed to assess the Minority Stress Model which proposes that the stress of experiencing stigma leads to adverse mental health outcomes, but social supports (e.g., school and family connectedness) will reduce this negative effect.

Methods: We measured stigma-related experiences, social supports, and mental health (self-injury, suicide, depression, and anxiety) among a sample of 923 Canadian transgender 14- to 25-year-old adolescents and young adults using a bilingual online survey. Logistic regression models were conducted to analyze the relationship between these risk and protective factors and dichotomous mental health outcomes among two separate age groups, 14- to 18-year-old and 19- to 25-year-old participants.

Results: Experiences of discrimination, harassment, and violence (enacted stigma) were positively related to mental health problems and social support was negatively associated with mental health problems in all models among both age groups. Among 14–18 year olds, we examined school connectedness, family connectedness, and perception of friends caring separately, and family connectedness was always the strongest protective predictor in multivariate models. In all the mental health outcomes we examined, transgender youth reporting low levels of enacted stigma experiences and high levels of protective factors tended to report favorable mental health outcomes. Conversely, the majority of participants reporting high levels of enacted stigma and low levels of protective factors reported adverse mental health outcomes.

Conclusion: While these findings are limited by nonprobability sampling procedures and potential additional unmeasured risk and protective factors, the results provide positive evidence for the Minority Stress Model in this population and affirm the need for policies and programs to support schools and families to support transgender youth.

title: Ngā kīrehu o Te Arawa ki Rotorua

authors: Morrison, Scott Jeffrey Tipene

subjects: Te reo Māori

abstract: Ko te reo Māori he reo tuauriuri whāioio, ā, he reo i kōhure ake i te whenua e kīa nei ko Aotearoa. Heoi anō, ka tae mai te Pākehā ki konei noho ai, ā, ka whārikihia ko ā rātou ture hei tauira tikanga mō ngā tāngata ki Aotearoa, ā, ko tō rātou reo hei reo whakaata whakaaro hei reo hoko parāoa hoki. I roto i ngā tau maha kua pahemo i raro i ēnei whakarite hou, kua memeha noa te reo Māori. Te mutu, i roto i ngā whakaakoranga hou i mahue ngā ahureitanga ake o te reo hei kawenga i te hihiri o te hinengaro Māori. Koinei ka tahuri ake au ki te whai i tētahi o ngā āhuatanga whakahirahira o te reo e mahue ana i roto i ngā akoranga i te reo hei reo tuarua.
Ko ngā kīrehu tētahi pekanga o te reo Māori kei te kaha te ngaro i te nuinga o ngā kaikōrero o te reo Māori o ēnei rā. Ki te waiho ērā momo kōrero kia moe, e kore e whakaara ake, ā, ko tōna mutunga, kua ngaro mō ake tonu atu. Kātahi tātou te ao Māori ka tangi mō tēnei āhuatanga nui o te reo ka ngaro i a tātou, ā, ko te rere a te ua koia anō kei te wai e riringi tonu nei te utu. Heoi anō, ki te mataara tātou, ki te whakaara ake i ēnei momo kōrero, ka whai kupu te reo Māori, ā, ka hoki mai te reo tuauriuri whāioio ki a tātou o tēnei reanga. Kei roto i ngā kīrehu e pupuri ana te wairua me te hinengaro Māori o ngā tūpuna o mua, arā, ka kite i te āhua o te whakaaro i roto i a rātou.
Ka tahuri ake au ki te whai i tēnei kaupapa kia whakaara ake anō ngā kīrehu kua roa e moe ana, ā, ki te kimi whakautu mō ētahi pātai i toko ake i te wā e whakaarohia ana te kaupapa nei. Tuatahi, i whakawhāiti taku titiro ki ngā kīrehu ake o Te Arawa waka e noho ana ki te rohe o Rotorua-nui-a-Kahumatamomoe. I pērā ai te whānui o taku titiro kia kore ai au e pokea e te kaupapa nei ka tahi, kia whakaara ake anō ai ngā kīrehu tūturu o tērā rohe kua tino roa nei e ngaro ana ka rua, ā, kia whakahoki mai ai ko aua kīrehu hei mahi mā tēnei reanga kōrero Māori kia ea ai te kōrero, "Ko Te Arawa māngai nui" ka toru. Tuarua, i whakawhānui ake taku titiro ki ngā kīrehu kei te mōhiotia e te motu.
Hei whakatutuki i taku kaupapa ka tirohia, ka wānangahia te kaupapa i raro i ngā upoko e whai ake nei. Kei te upoko tuatahi he whakamārama he aha au i whai ai i taku kaupapa mō ngā kīrehu. Kei te upoko tuarua he āta whakamārama i te kīrehu me ōna tikanga katoa, me ngā rerekētanga i waenganui i te kīrehu me ana hoa me te kīwaha, te huahuatau, te kupu whakarite, me te whakataukī. Ka titiro hoki ki ngā wāhi ka rangona, ka whakamahia rānei te kīrehu. Kei te upoko tuatoru ka tirohia ngā kīrehu kua kitea. E rua ngā wāhanga o tēnei upoko. Kei te wāhanga tuatahi ko ngā kīrehu o Te Arawa ki Rotorua me ā rātou whakamārama, kei te wāhanga tuarua ko ngā kīrehu o te motu whānui kua whakaraupapahia i raro anō i ngā upoko e whakaatu ana i te tikanga o ia kīrehu, me ā rātou whakamārama. Kei te whakamutunga ko te whakarārangi me te tūhonohono ake i ngā kitenga katoa i roto i aku rangahau, i aku wherawheratanga i te kaupapa nei me ngā hua ka puta ki te whāia ngā kīrehu i roto i ngā akoranga ki te hunga kātahi anō ka tahuri mai ki te whai i te reo Māori hei reo tuarua.
Kei konei ka whai wāhi ki te whakamārama i te huarahi i whāia e tutuki ai te kaupapa o tēnei mahi rangahau. I te wā e whakaarohia ana te kaupapa nei ka puta te whakaaro ki roto i a au kia kōrero tahi me ngā koroheke nō roto o Te Arawa waka, kia pātaihia rātou ki ō rātou mōhiotanga e pā ana ki tēnei kaupapa, me ngā kīrehu e mōhio ana rātou, kei te whakamahia rānei e rātou. Ka mutu, kia kōrero hoki ki ngā tāngata wetewete reo, ki ngā tāngata matatau, ki te rangatahi, me ngā koroheke o ngā iwi i waho atu o Te Arawa. Ehara i te mea he aha, heoi anō ki a au kāore kē he huarahi i tua atu i te kōrerorero-ā-tangata hei awhi i te rangahau o tēnei kaupapa. I pēnā ai te whakaaro nā te mea, ki a au ko te kīrehu he mea ka rangona i roto i ngā kōrerorero a te tangata, ā, he mea kāore e tino tuhituhi ana. Nā reira, i āta whakaaro au ko ngā wāhi kōrerorero noa a te tangata pea, ngā wāhi pai kia rapu mai i ēnei tūmomo kōrero. Nā, i whāia tēnei huarahi e au, ā, i tino whai hua tēnei o ngā huarahi. I kitea, i rangona ētahi kōrero whakamārama me ētahi o ngā kīrehu o Te Arawa i konei. Tāpiri atu ki tēnā, i rangona ngā whakaaro me ngā kōrero a ngā momo tāngata katoa, rangatahi mai, koroheke mai.
I tua atu i te kōrero tahi, arā anō ngā huarahi i whāia. I pūhia au e ngā hau kōhengihengi a Tāwhirimātea kia tae atu ki ngā tōpito katoa o Te Ika Roa a Māui; ki ngā whare pukapuka i Tāmaki, i Te Whanganui a Tara, i Kirikiriroa, i Pāmutana, i Rotorua. Hei aha? Hei āta rangahau i ngā kōrero e pā ana ki tēnei kaupapa. I reira i kitea ngā rīpoata tawhito me ngā rīpoata hou, ngā kohinga kōrero o namata, o nāianei hoki, me ngā reta i tuhia e ngā rangatira i tērā rautau, me ngā rārangi pukapuka e pupuri ana ngā kōrero o mua. I haere au ki Te Kōti Whenua Māori i Rotorua ki te pānui ngā kōrero e whakaatu ana i te noho a te Māori i ngā rā o nehe, me ngā kōrero i whakatakotohia e rātou ki mua i te aroaro o te kōti. I roto i ēnei tuhinga e mau ana ētahi kīrehu i whakahua ake i te wā i hui ai ngā tūpuna mō te whenua te kaupapa. Kei aua wāhi nui anō, arā, kei Tāmaki me Te Whanga Nui a Tara, e puritia ana ētahi tēpa kei runga nei ngā kōrero a ngā rangatira kua whetūrangitia. I tonoa kia whakarongo pīkari aku taringa ki ēnei tēpa, ā, i puta mai ētahi kīrehu i aua tēpa rā.
Nā ēnei momo huarahi i taea ai te whakaemi me te whakakao i ngā whakaaro me ngā kōrero katoa o tēnei tuhinga, ā, te putanga atu, kua whakarārangihia ngā kōrero, ngā whakaaro me ngā kīrehu i kitea mai, i rangona mai, i puta mai. 
Heoi anō, kāore te wai i marino i ngā wā katoa. I ētahi wā ka tae mai he raruraru, he uauatanga hei whakapakeke i te ara, he ngārara rānei hei whakapae i te huarahi. Ka pōuri te manawa nā te mea kāore au i whai wāhi ki te kōrero ki a Irirangi Tiakiawa rāua ko Tāmati Wharehuia i mua i tō rāua wehenga. I te whakatikatika au i a au anō ki te kōrero ki a Irirangi kātahi ia ka mate. Ka whakatika anō au ki te kōrero ki a Tāmati, ā, ka mate hoki tērā. Kāore e kore he kōrero, he mōhiotanga ā rāua hei whakamōmona i te tuhinga nei, engari e taea te pēhea? Ko tēnei mea te mate e kore e taea te karo, engari, i runga i tēnā āhua, kei te tangi tonu te mapu, kei te pōuri tonu te manawa.
I tua atu i tēnā, ka raruraru au i te korenga ōku e tino kite ngā kīrehu i roto i ngā tuhinga a te tangata. E tika ana te whakaaro, kāore ngā kīrehu e tino tuhituhi ana. I kitea ētahi i roto i ngā tuhinga, engari me uaua ka kitea mai ērā. E hia kē ngā hāora i whakapaua e au kia rapua mai ngā kīrehu e huna ana i roto i ngā pukapuka, i ngā reta, otirā i ngā momo tuhinga katoa a te tangata.
Ahakoa ēnei, he nui ngā painga i puta mai ki a au i roto i tēnei mahi rangahau. Ka mīharo katoa te kōrero tahi me ngā koroheke, i reira i āta rangona te reo o ngā mata o te ao kōhatu, me kī, te reo tuauriuri whāioio. I puta mai i a rātou ngā whakaaro tūturu o te hinengaro Māori tūturu hei awhi i te hanga o tēnei mahi rangahau. I pai anō rā taku haere ki te Whare Pukapuka o Turnbull i reira e pupuri ana ngā kōrero me ngā whakaahua a tua whakarere. I ētahi wā, nā te nui o ngā momo tuhinga Māori ātaahua i roto i taua whare pukapuka, ka titi taku haere ki kaupapa kē. Ahakoa i reira au mō te wiki kotahi, kāore rawa i oti i a au ngā tuhinga i hiahia au ki te pānui. Ko tētahi atu mea pai i puta mai ki a au i roto i tēnei mahi rangahau, ko te akoako i ētahi kīrehu, i ētahi kīwaha me ētahi whakataukī hou hei whakamahi māku i ngā wā e kōrero Māori ana au, me te whēkite o ētahi tuhinga Māori kāore anō au kia kite noa.
Heoi anō hei whakakapi i tēnei wāhanga, i hangaia mai tēnei pūtoi kīrehu hei whakaara ake i ngā kīrehu o Te Arawa ki Rotorua ka tahi, hei hua mā te hunga e ako ana i te reo Māori hei reo tuarua kia whai kupu tō rātou reo ka rua, hei whakahoki i ngā pātai i toko ake ai i te wā e whakaaroarohia ana tēnei kaupapa ka toru. Ināianei ka riro mā ngā kōrero, mā ngā tuhinga me ngā whakaaro kei te whai mai e whakatinana te kaupapa o tēnei mahi rangahau.

I kitea ētahi i roto i ngā tuhinga, engari me uaua ka kitea mai ērā. E hia kē ngā hāora i whakapaua e au kia rapua mai ngā kīrehu e huna ana i roto i ngā pukapuka, i ngā reta, otirā i ngā momo tuhinga katoa a te tangata.
Ahakoa ēnei, he nui ngā painga i puta mai ki a au i roto i tēnei mahi rangahau. Ka mīharo katoa te kōrero tahi me ngā koroheke, i reira i āta rangona te reo o ngā mata o te ao kōhatu, me kī, te reo tuauriuri whāioio. I puta mai i a rātou ngā whakaaro tūturu o te hinengaro Māori tūturu hei awhi i te hanga o tēnei mahi rangahau. I pai anō rā taku haere ki te Whare Pukapuka o Turnbull i reira e pupuri ana ngā kōrero me ngā whakaahua a tua whakarere. I ētahi wā, nā te nui o ngā momo tuhinga Māori ātaahua i roto i taua whare pukapuka, ka titi taku haere ki kaupapa kē. Ahakoa i reira au mō te wiki kotahi, kāore rawa i oti i a au ngā tuhinga i hiahia au ki te pānui. Ko tētahi atu mea pai i puta mai ki a au i roto i tēnei mahi rangahau, ko te akoako i ētahi kīrehu, i ētahi kīwaha me ētahi whakataukī hou hei whakamahi māku i ngā wā e kōrero Māori ana au, me te whēkite o ētahi tuhinga Māori kāore anō au kia kite noa.
Heoi anō hei whakakapi i tēnei wāhanga, i hangaia mai tēnei pūtoi kīrehu hei whakaara ake i ngā kīrehu o Te Arawa ki Rotorua ka tahi, hei hua mā te hunga e ako ana i te reo Māori hei reo tuarua kia whai kupu tō rātou reo ka rua, hei whakahoki i ngā pātai i toko ake ai i te wā e whakaaroarohia ana tēnei kaupapa ka toru. Ināianei ka riro mā ngā kōrero, mā ngā tuhinga me ngā whakaaro kei te whai mai e whakatinana te kaupapa o tēnei mahi rangahau.
