Associates

Defnyddiodd yr Athro Marc Roussel (ar absenoldeb sabothol o Lethbridge, Alberta) sbectrometreg màs fewnfa bilen i ddatgelu'r attractor rhyfedd sy'n sail i ddeinameg resbiradol burum mewn diwylliant parhaus. Roedd hyn yn gofyn am fonitro ar yr un pryd H2S, CO2 ac O2; Caffaelwyd 40,000 o bwyntiau ar gyfnodau 15 mewn arbrawf diwylliant parhaus 3 mis. Dyma'r arddangosiad diamwys cyntaf o reolaeth ddiamwys mewn system fiolegol ar lefel celloedd cyfan.

Sefydlodd Dr Katey Lemar fecanweithiau ar gyfer priodweddau gwrth-candidal cydrannau garlleg dethol, mae alcohol diallyldisulphide ac allyl yn cynhyrchu marwolaeth celloedd apoptotig yn yr organeb hon heb fod yn rhy wenwynig i bobl. Mae hyn yn cynnig ffordd newydd o fynd i'r afael ag ymwrthedd i wrthfiotigau; Nid oes unrhyw achosion o ficro-organebau yn dod yn gwrthsefyll cyfansoddion garlleg.

Astudiodd Dr Catrin F . Williams gyda Neem Biotechnology (Dr David Williams, Dr Gareth Evans, Dr Robert Saunders a Dr MIchael Graz), yr Athro Jo Cable a Dr Michael P. Coogan i astudio biocemeg a heintusrwydd y protozoan, Vortens Spironucleus tuag at bysgod angel, yn enwedig sensitifrwydd y parasit i gyfansoddwyr garlleg.

Gyda'r Athro Adrian Porch (Peirianneg), mae Catrin ar hyn o bryd yn astudio effeithiau a'u mecanweithiau o ficrodonnau 2.45 GHz ar fioymoleuedd y bacteriwm morol, Vibrio fischeri ac ar linellau celloedd dynol normal a chanseraidd diwylliedig.

Cyn Gymdeithion Diweddar

Mae Dr Stefanie Scheerer a Dr Francisco Gomez wedi sefydlu diwylliant parhaus sefydlog o bysgota Ffotobacteriwm. Gellir defnyddio hyn fel monitor ar-lein ar gyfer cyfansoddion gwenwynig (ee bioladdiadau) mewn samplau amgylcheddol gan gynnwys cyflenwadau dŵr. Bydd miniaturization yn arwain at ddatblygu systemau diogelu personol. Astudiwyd effeithiau microdonnau.

Dangosodd Dr Simon Cottrell fod rhewi powdr garlleg sych yn wenwynig i MRSA, ac y gallai effeithiau synergaidd ar y cyd ag ocsicillin ddarparu strategaeth chemotherapiwtig newydd.

Mae Dr Victoria Gray wedi dangos bod morffoleg rhywogaethau Salmonela typhimurium a poona yn dibynnu'n barhaus ar gynnwys tyrosin y cyfrwng twf. Gall ffynonellau amrywiol o'r peptone a ddefnyddir yn y cyfryngau diagnostig cymhleth fod yn eithaf anaddas oherwydd eu diffyg tyrosin. Mae organebau aflagellate, na ellir eu hadnabod fel y pathogen, yn arwain os nad yw'r cyfrwng yn addas.

Ymchwiliodd Dr Kristina Harris i effeithiau difluoro methylornithine ar dwf, strwythur a swyddogaeth Trichomonas vaginalis. Mae hydrogenosemes diffygiol yn un o ganlyniadau yr atalydd decarboxylase ornithine hwn.

Ymchwiliodd Dr Jonathan Wood i gymhwyso garlleg fel gwrthfacterol yn benodol yn erbyn MRSA. Datrys effeithiau sy'n ofynnol gwahanu'r prif gyfansoddion gwenwynig; ymchwiliwyd synergedd gyda deilliadau penisilin.

Ymchwiliodd Dr Coralie Millet i barasitiaid pysgod protozoal Hexamita a Spironucleus spp. Y farchnad ar gyfer fiticulture o bysgod acwariwm yw $ 7b / an. Pathogenicity ac ymyrryd; Astudiwyd bioamrywiaeth a'i gymharu â bioamrywiaeth rhywogaethau sy'n byw yn rhydd.
