2. 1. Functional Analysis of the Vesicular Glutamate Transporter 2 in Specific Neuronal Circuits of the Brain

   Author : Karin Nordenankar; Åsa Wallén-Mackenzie; Rainer Spanagel; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Addiction; amphetamine; affective behaviour; cocaine; cognitive behaviour; conditional knockout mouse; dopamine; operant self-administration; reward system; schizophrenia; Neuroscience; Neurovetenskap;

   Abstract : A key issue in neuroscience is to determine the connection between neuronal circuits and behaviour. In the adult brain, all neuronal circuits include a glutamatergic component. READ MORE

4. 2. Motion and Emotion : Functional In Vivo Analyses of the Mouse Basal Ganglia

   Author : Emma Arvidsson; Åsa Wallén-Mackenzie; Cecilia Flores; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dopamine; Basal Ganglia; Reward System; In Vivo Chronoamperometry; Optogenetics; Deep Brain Stimulation; Parkinson’s Disease; Addiction; Glutamate; Vesicular Glutamate Transporter; VGLUT2; Sex; Age; Subthalamic Nucleus; Striatum; Nucleus Accumbens; Ventral Tegmental Area;

   Abstract : A major challenge in the field of neuroscience is to link behavior with specific neuronal circuitries and cellular events. One way of facing this challenge is to identify unique cellular markers and thus have the ability to, through various mouse genetics tools, mimic, manipulate and control various aspects of neuronal activity to decipher their correlation to behavior.

5. 3. Glioma as an Ecosystem : Studies of Invasion, Onco-miR Addiction and Mast Cell Infiltration

   Author : Jelena Põlajeva; Bengt Westermark; Ingemar Ernberg; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glioblastoma; mast cell; miR-21; RAP1; CXCL12; SOX2;

   Abstract : Despite recent advances in oncology and extensive research efforts, gliomas remain essentially incurable. Glioblastoma multiforme (GBM, WHO grade IV) is the most common glioma and may arise de novo or progress from a lower-grade lesion. GBM is characterized by invasive growth, aberrant angiogenesis and necrosis. READ MORE

6. 4. Problematic Gaming and Gambling among Adolescents

   Author : Sofia Vadlin; Kent W Nilsson; Cecilia Åslund; Erika Comasco; Clara Hellner Gumpert; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescent; anxiety; attention deficit hyperactivity disorder; depression; gambling; gaming; psychometrics; Child and Youth Psychiatry; Barn- och ungdomspsykiatri;

   Abstract : The overall aims of this thesis were to develop and evaluate a screening instrument designed to detect gaming addiction symptoms in adolescents, to study associations between problematic gaming and psychiatric symptoms, to investigate the stability of problematic gaming, and to examine possible associations between gaming at baseline (W1) with problem gambling three years later (W2).The study population consisted of adolescents from the Survey of Adolescent Life in Västmanland SALVe Cohort (adolescents in Västmanland born in 1997 and 1999, and their parents), in two waves (2012, n = 1887; 2015, n = 1576), and adolescents from child and adolescent psychiatric clinics in Västmanland (2014, n = 242).

7. 5. From Food Preference to Craving : Behavioural Traits and Molecular Mechanisms

   Author : Johan Alsiö; Helgi B Schiöth; Jonas Lindblom; Anna M Kindlundh-Högberg; Suzanne Dickson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obesity; Reward; Food preferences; Dietary fats; Dietary carbohydrates; Anxiety; Dopamine; Craving; Operant self-administration; Pharmacology; Farmakologi; Farmakologi; Pharmacology;

   Abstract : Preference for palatable and energy-dense foods may be a risk factor for body weight gain and has both genetic and environmental components. Once obesity develops in an individual, weight loss is difficult to achieve. READ MORE
