The fat-derived hormone adiponectin alleviates alcoholic and nonalcoholic fatty liver diseases in mice
Adiponectin has recently been shown to be a promising candidate for the treatment of obesity-associated metabolic syndromes. Replenishment of recombinant adiponectin in mice can decrease hyperglycemia, reverse insulin resistance, and cause sustained weight loss without affecting food intake. Here we report its potential roles in alcoholic and nonalcoholic fatty liver diseases in mice. Circulating concentrations of adiponectin decreased significantly following chronic consumption of high-fat ethanol-containing food. Delivery of recombinant adiponectin into these mice dramatically alleviated hepatomegaly and steatosis (fatty liver) and also significantly attenuated inflammation and the elevated levels of serum alanine aminotransferase. These therapeutic effects resulted partly from the ability of adiponectin to increase carnitine palmitoyltransferase I activity and enhance hepatic fatty acid oxidation, while it decreased the activities of two key enzymes involved in fatty acid synthesis, including acetyl-CoA carboxylase and fatty acid synthase. Furthermore, adiponectin treatment could suppress the hepatic production of TNF-α and plasma concentrations of this proinflammatory cytokine. Adiponectin was also effective in ameliorating hepatomegaly, steatosis, and alanine aminotransferase abnormality associated with nonalcoholic obese, ob/ob mice. These results demonstrate a novel mechanism of adiponectin action and suggest a potential clinical application of adiponectin and its agonists in the treatment of liver diseases.published_or_final_versio

Developing Burrowing As A Non-Evoked Readout Assessment For Novel Analgesic Drug Efficacy
Traditional drug development efforts to diminish the problem of chronic pain rely heavily on pain-evoked assays that can yield false positives, leading to confounding assessments of novel drugs. To avoid this, we are looking at burrowing as a novel readout assessment of analgesic efficacy. Preliminary data shows that induction of post-surgical pain reduces this innate behavior by about 35%. In attempt to increase this number, we tested a variety of additional parameters. Blue pads, placed at the bottom of each chamber in order to reduce the sound made when gravel is displaced, increased baseline amounts roughly 40%. Conversely, neither sex of the animal, nor time of day the experiment was performed was found to have an affect on the amount burrowed. Further optimizations of this assay look at habituation and test session length. We found that a 5-day habituation regiment could not be shortened, but a test session length of 15min produced comparable results to the original 60min session. Current studies are aimed at using HD webcams to quantify additional behaviors such as time spent burrowing and time spent in the tube. Ultimately, these studies could lead to the development of a beneficial assay for use in assessing novel analgesic drugs.https://dune.une.edu/neuro_studpost/1000/thumbnail.jp

Hur göra ett efterarbete som ger deltagarna mod att öppna sig
Syftet med detta examensarbete var att undersöka hur jag kunde genomföra och utveckla ett efterarbete för en föreställning som handlar om existentiella frågor. Jag försökte utveckla ett efterarbete som ger deltagarna mod att öppna upp sig, för att diskutera ämnen som berör och är känsliga för mottagaren. Mitt mål var att skapa ett efterarbete som ger deltagarna mod att till och med våga dela med sig om sina egna existentiella problem.
Forskningsfrågor:
1. Hur skapas ett tryggt utrymme, en miljö där deltagarna känner sig sedda och respekterade?
2. Hur gör vi en design för efterarbetet som inbjuder till att dela sina tankar öppet för
varandra?
I detta arbete undersöker jag de två workshopparna som vi höll efter föreställningarna av vår pjäs, Kun vielä oli pimeä,som var mitt konstnärliga examensarbete. Via empirisk forskning med kvalitativ metod analyserade jag den skriftliga och muntliga feedbacken från deltagarna samt videomaterialet vi filmade under workshopparna för att utveckla dem. Dessutom analyserade jag mig själv som ledare kritiskt med hjälp av videomaterialet.
Resultatet av min skrivprocess är att ett efterarbete aldrig är färdigt utan befinner sig alltid i en permanent utvecklingsprocess, även om man skulle hållit workshoppen hundra gånger. Nödvändigheten av kontaktövningar i början av en workshop med människor som är obekanta med varandra är det andra viktiga resultatet
