- The distribution of galanin mRNA-expressing cells and galanin-immunoreactive (IR) cell bodies and processes was studied in the brain of mice overexpressing galanin under the PDGF-B promoter (GalOE mice) and of wild type (WT) mice, both in colchicine-treated and non-treated animals. In this abstract, we only describe the results in GalOE mouse. A widespread ectopic expression of galanin (both mRNA and peptide) was found, that is a situation when neither transcript nor peptide could be seen in WT mice, not even after colchicine treatment. However, in some regions, such as claustrum, basolateral amygdala, thalamus, CA1 pyramidal cells, and Purkinje cells only galanin mRNA could be detected. In the forebrain galanin was seen in the mitral cells of the olfactory bulb, throughout the cortex, in the basolateral amygdaloid nucleus, claustrum, granular and pyramidal cell layers of the hippocampus, subiculum and presubiculum. In the thalamus, the anterodorsal, mediodorsal, intermediodorsal and mediodorsal lateral nuclei, the reuniens and reticular nuclei showed ectopic expression of galanin. Within the hypothalamus, neurons of the suprachiasmatic nucleus contained galanin. In the mesencephalon, the geniculate nucleus, nucleus ruber, the mesencephalic trigeminal and reticulotegmental nuclei ectopically expressed galanin. In the cerebellum, galanin was observed in the Purkinje cells and in the lateral and interposed cerebellar nuclei. In the pons, sensory and motor nuclei of the trigeminal nerve, the laterodorsal and dorsal tegmental nuclei, the pontine, reticulotegmental and gigantocellular reticular nuclei expressed galanin. Within the medulla oblongata, labeled cells were detected in the facial, ambiguus, prepositus, lateral paragigantocellular and lateral reticular nuclei, and spinal trigeminal nucleus. High densities of galanin-IR fibers were found in the axonal terminals of the lateral olfactory tract, the hippocampal and presumably the cerebellar mossy fibers system, in several thalamic and hypothalamic regions and the lower brain stem. Possible functional consequences of galanin overexpression are discussed.

Laurells Klinisk kemi i praktisk medicin
- 2012. - 9
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Klinisk kemi i praktisk medicin används som kurslitteratur för läkare, biomedicinska analytiker och biomedicinare sedan 40 år tillbaka. Den finns på avdelningar, mottagningar och vårdcentraler - överallt där man behöver ta prover för kliniskt kemiska analyser och tolka deras resultat. Nu föreligger den i sin nionde upplaga efter omfattande revision och med nyskrivna kapitel. I denna upplaga har innehållet organiserats med tydlig anknytning till kliniska problemområden. Alla kapitel har grundligt reviderats. Avsnitten om tolkning av analysresultat, allergi och autoimmunitet, hjärtinfarkt och hjärtskademarkörer, digestionsorganens sjukdomar, graviditet, infertilitet och prenataldiagnostik samt läkemedel, förgiftningar och missbruk är helt nyskrivna. Boken kan användas både för att slå upp fakta om specifika analyser och för att förstå de sjukdomsmekanismer som är av betydelse för tolkningen av laboratorieresultat. Modern medicinsk praxis är patientcentrerad och har sitt fundament i ett nära samspel mellan klinik, laboratorier och patienter. Kunskapsfragment inom klinisk kemi är lättillgängliga för alla och envar på nätet, men ger sällan den helhetsbild som behövs för grundlig förståelse och därmed optimal användning av laboratorieanalyser. Denna bok ger sådan helhetsbild.

Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Denna tionde upplaga av Laurells Klinisk kemi i praktisk medicin utgör en grundlig bearbetning av det populära verket. Samtliga kapitel har reviderats och kapitlen om tolkning av analysresultat, vatten, elektrolyter, blodgaser, mag–tarmkanalen och immunologi har skrivits om från grunden; allt i samarbete mellan verksamma inom klinisk farmakologi, klinisk immunologi och klinisk kemi.?Kunskapsfragment inom medicin, inklusive klinisk kemi, är lättillgängliga på nätet men ger sällan den helhetsbild som behövs för en djupare förståelse och därmed optimal användning av laboratorieanalyser. Denna bok ger en sådan helhetsbild och kan användas såväl för att slå upp fakta om specifika analyser som för att förstå de sjukdomsmekanismer som är av betydelse för beställning och tolkning av laboratorieresultat.?Texten är organiserad utifrån kliniska problemområden och i balansgången mellan inslagen av laboratorium och medicin har tonvikten lagts på det medicinskt-diagnostiska snarare än på det laboratorietekniska. Fokus ligger på förståelsen av preanalytiska och analytiska faktorer vid tolkningen av laboratorieresultat samt av förståelsen av prevalens, sensitivitet, specificitet och liknande begrepp i det diagnostiska arbetet.?Föreliggande bok förväntas även fortsatt komma till god användning på avdelningar, mottagningar och vårdcentraler – överallt där man behöver ta laboratorieprover och tolka provsvar – men också bland studenter i medicin, biomedicin, biomedicinsk laboratorievetenskap och besläktade kunskapsområden.

- Studies show that very low birthweight can be an important risk factor for mental problems, disturbed fertility and neuroendocrine dysregulation. In a regional long-term study 56 of 86 adult individuals 27 to 28 years of age with a very low birthweight were compared with normal birthweight controls. Analyses of self-reported mental health, socio-demographic factors, sex hormone levels, and hair cortisol levels showed no significant differences between the groups. However, in order to analyse subgroups with different risk factors from the newborn period or children with a variety of social background factors, larger patient groups are needed.

- AimTo assess mental health outcomes of very low birthweight (VLBW, <1500 g) subjects to adulthood and to examine salivary cortisol and hair cortisol levels and their relation to birth characteristics and mental health.MethodsA Swedish regional cohort of 56 VLBW subjects and 55 full‐term controls were assessed at the ages 27‐28 with adult self‐reported scales and the mean of 2 days diurnal salivary cortisol and hair cortisol. The cohorts had been assessed at 15 years of age with youth self‐reported scales.ResultsThere were no differences between the groups in youth self‐reported scales and adult self‐reported scores. The 24 participating VLBW girls scored lower on youth self‐reported scales externalising and total problem scores than the control girls. In adulthood, the 21 participating VLBW women had significantly higher morning concentrations of salivary cortisol than control women, P = .014. No significant associations were found between cortisol concentrations and adult self‐reported scales internalising, externalising and total scores.ConclusionSelf‐reported mental health in VLBW subjects was comparable with normal birthweight controls indicating a satisfying transition from adolescence to adulthood. VLBW females had higher morning salivary cortisol concentrations, suggesting a gender difference. We found no correlations between cortisol and mental health.

- Purpose: Stress and/or anxiety during pregnancy affect maternal and fetal wellbeing and can cause premature delivery and postnatal pathology in the child. Women suffering from phobias related to blood and injections are prone to high levels of stress including anxiety and sometimes panic attacks during pregnancy. Cortisol is amongst the mediators through which the neurohormonal expressions of maternal psychological factors may be transduced to the fetus. The aim was to investigate if pregnant women suffering from blood- and injection phobia have raised cortisol levels or are characterized by unusual diurnal salivary cortisol profiles compared to healthy controls. Methods: The sample consisted of 110 pregnant women with blood- and injection phobia and 110 pregnant healthy controls. Both groups provided morning and evening saliva samples in week 25 and 36 for the assay of cortisol. In gestational week 25 when blood was drawn for the mandatory blood testing extra blood was taken to analyze corticotrophin releasing factor (CRF), adrenocorticotropic hormone (ACTH) and cortisol in serum. Results: The expected diurnal decline in salivary cortisol was observed as well as increased cortisol levels during pregnancy. Pregnant women suffering from blood- and injection phobia had higher output of cortisol compared to women without the phobia (F=6.25 df=1 p=0.014) but no marked difference in the diurnal cortisol rhythm was found between the groups. Conclusion: Our findings indicate that untreated blood- and injection phobia during pregnancy increases cortisol concentrations. Blood- and injection phobia is treatable and cognitive behavioral therapy can be used.

Linearity assessment: deviation from linearity and residual of linear regression approaches
- 2024

Tidskriftsartikel (refereegranskat)abstract
- In this computer simulation study, we examine four different statistical approaches of linearity assessment, including two variants of deviation from linearity (individual (IDL) and averaged (AD)), along with detection capabilities of residuals of linear regression (individual and averaged). From the results of the simulation, the following broad suggestions are provided to laboratory practitioners when performing linearity assessment. A high imprecision can challenge linearity investigations by producing a high false positive rate or low power of detection. Therefore, the imprecision of the measurement procedure should be considered when interpreting linearity assessment results. In the presence of high imprecision, the results of linearity assessment should be interpreted with caution. Different linearity assessment approaches examined in this study performed well under different analytical scenarios. For optimal outcomes, a considered and tailored study design should be implemented. With the exception of specific scenarios, both ADL and IDL methods were suboptimal for the assessment of linearity compared. When imprecision is low (3 %), averaged residual of linear regression with triplicate measurements and a non-linearity acceptance limit of 5 % produces <5 % false positive rates and a high power for detection of non-linearity of >70 % across different types and degrees of non-linearity. Detection of departures from linearity are difficult to identify in practice and enhanced methods of detection need development.

Molecular Fingerprint of Neuropeptide S-Producing Neurons in the Mouse Brain

- Neuropeptide S (NPS) has been associated with a number of complex brain functions, including anxiety-like behaviors, arousal, sleep-wakefulness regulation, drug-seeking behaviors, and learning and memory. In order to better understand how NPS influences these functions in a neuronal network context, it is critical to identify transmitter systems that control NPS release and transmitters that are co-released with NPS. For this purpose, we generated several lines of transgenic mice that express enhanced green-fluorescent protein (EGFP) under control of the endogenous NPS precursor promoter. NPS/EGFP-transgenic mice show anatomically correct and overlapping expression of both NPS and EGFP. A total number of similar to 500 NPS/EGFP-positive neurons are present in the mouse brain, located in the pericoerulear region and the Kolliker-Fuse nucleus. NPS and transgene expression is first detectable around E14, indicating a potential role for NPS in brain development. EGFP-positive cells were harvested by laser-capture microdissection, and mRNA was extracted for expression profiling by using microarray analysis. NPS was found co-localized with galanin in the Kolliker-Fuse nucleus of the lateral parabrachial area. A dense network of orexin/hypocretin neuronal projections contacting pericoerulear NPS-producing neurons was observed by immunostaining. Expression of a distinct repertoire of metabotropic and ionotropic receptor genes was identified in both NPS neuronal clusters that will allow for detailed investigations of incoming neurotransmission, controlling neuronal activity of NPS-producing neurons. Stress-induced functional activation of NPS-producing neurons was detected by staining for the immediate-early gene c-fos, thus supporting earlier findings that NPS might be part of the brain stress response network.
