Abstract
Communication has long been associated with the well-being of a couple's relationship, and it is also important to explore associations with individual well-being. This study examined the associations between emotions communicated within couple interactions and each partner's psychopathology symptoms concurrently and up to 3 years later. Vocally-encoded emotional arousal (f₀) was measured during couples' (N = 56) conversations. Analyses examined each partner's trajectories of f₀ and how each partner influenced the other's f₀ across the conversation. The findings indicated that women experienced higher symptoms if they (a) decreased more steeply in f₀ overall and (b) returned to their baseline in f₀ more quickly. Moreover, women had higher symptoms if they had a steeper return to baseline because of men's elevated f₀. In contrast, men experienced higher symptoms when men (a) more slowly returned to baseline and (b) changed their f₀ trajectory because of women's elevated f₀. That is, women who expressed less emotional arousal, independently and as a result of the influence of their male partner, experienced more symptoms. In contrast, men's symptoms were differentially associated with their own independent experience of emotional arousal (in which he experienced fewer symptoms when changing arousal more quickly) from how they responded to women's arousal. Given how differently men's and women's psychopathology were associated with emotional expression, these findings raise questions about how partners can communicate to protect their own and their partner's mental health in the short- and long-term.

Abstract
Relationship distress and divorce are major risk factors for the development or exacerbation of psychopathology and psychosocial impairments. Given that heightened negative emotions within couples' interactions may portend negative relationship outcomes, it is critical to understand how emotions unfold across a conversation and how partners may influence each other's immediate emotional experiences. This study examined whether these regulatory dynamics within one interaction predicted relationship satisfaction concurrently and 25 years later. Vocally-encoded emotional arousal (f0 ) was measured during couples' (N = 25 couples) conversations about a relationship issue. Across different analytical strategies, results demonstrate that one partner's f0 dynamics had immediate and long-term associations with the other partner's satisfaction. Partners were less satisfied if the other partner (a) expressed higher f0 overall and (b) escalated more in f0 across the conversation. Yet, partners were more satisfied when their f0 escalated across the conversation. Also, women specifically were more satisfied if their f0 remained elevated longer before regulating back to their emotional baseline. Thus, higher f0 was associated with higher satisfaction in the same partner, but associated with less satisfaction in the other partner-particularly when these emotions come from women. It may be that partners have to decide whether to prioritize expressing their emotions fully or limit expression in the service of their partner's happiness. These findings challenge us to think of ways to address this "win-lose" scenario so that couples can balance both partners' emotional needs and preserve relationship quality across the life span.

Abstract
Zusammenfassung. Theoretischer Hintergrund: Die Qualität der partnerschaftlichen, verbalen Kommunikation ist ein entscheidender Faktor für Trennung und Scheidung. Durch Konjunktionen können Satzteile sinnvoll miteinander verknüpft und Beziehungen zwischen ihnen hergestellt werden. Fragestellung: Lässt sich anhand von in Konfliktgesprächen verwendeten Konjunktionen die Scheidungswahrscheinlichkeit und die Partnerschaftszufriedenheit von Ehepaaren nach fünf und 25 Jahren vorhersagen? Methode: Zur Untersuchung dieser Hypothesen wurden 172 Transkripte von N = 65 zufriedenen Ehepaaren linguistisch ausgewertet. Ergebnisse: Mithilfe von logistischen und linearen Regressionsmodellen konnte gezeigt werden, dass die verwendeten Konjunktionen einen signifikanten Prädiktor (Schutzfaktor) für die Vorhersage der Scheidungswahrscheinlichkeit darstellen. Zur Vorhersage der Partnerschaftszufriedenheit eigneten sie sich hingegen zu keinem der beiden Untersuchungszeitpunkte. Schlussfolgerungen: Insgesamt stellte der Konjunktionsgebrauch einen Indikator für komplexe soziale Interaktionsprozesse dar.

Abstract
OBJECTIVE Pronounced weight loss after bariatric surgery was demonstrated to have significant beneficial effects on surrogates of early atherosclerosis. The aim of this prospective examination was to investigate whether these improvements of endothelial function and vascular structure are persistent in the long-term. DESIGN AND METHODS A total of 52 obese adults were examined before and 5 years after bariatric surgery. Carotid intima media thickness (IMT), brachial flow-mediated dilation (FMD), abdominal fat distribution, and metabolic parameters were determined. Additional 18 months data were available from 27 patients. RESULTS After 5 years, mean weight loss ± SD of 25% ± 12 in all subjects was accompanied by known improvements in metabolism. Change in IMT was -0.02 mm ± 0.007, whereas FMD improved by +1.5% ± 0.5. In the subgroup IMT decreased by 0.04 mm ± 0.06 within the first 18 months, whereas no significant change was observed between 18 month and 5 years. FMD improved by 3.8% ± 0.6 after 18 months followed by a nonsignificant decrease of -1.4% ± 0.9. CONCLUSIONS These long-term results demonstrate that bariatric surgery-induced weight loss improves both functional and structural markers of early atherosclerosis providing further evidence for the beneficial effects of weight loss on obesity-associated alterations of the vasculature.

Abstract
BACKGROUND AND AIMS Elevated plasminogen activator inhibitor 1 (PAI-1) concentrations are a hallmark of obesity and are considered to contribute to the development of cardiovascular disease. As adipose tissue constitutes a major source for PAI-1 in obesity, we investigated the individual contribution of subcutaneous and intra-abdominal fat on PAI-1 concentrations during pronounced weight loss after bariatric surgery. METHODS AND RESULTS Thirty-seven obese adults were examined before and 18 months after surgery. Abdominal fat distribution was determined by ultrasound, metabolic parameters and plasma PAI-1 levels by standard methods. BMI was reduced by 9.2 ± 4.9 kg/m(2), while total fat mass and visceral fat diameter (VFD) decreased by 20.7 ± 11.9 kg and 4.2 ± 2.3 cm, respectively. Concomitantly, PAI-1 levels diminished by 3.2 ± 5.6 ng/ml (all p ≤ 0.015). Change in PAI-1 levels was correlated with change in VFD (r = 0.441, p = 0.008), but not with subcutaneous fat diameter. In stepwise multiple regression analysis change in VFD was an independent predictor of change in PAI-1 concentrations. When adjusted for age and sex or total fat mass associations between PAI-1 and VFD remained significant. CONCLUSION We demonstrate that VFD is a major determinant for PAI-1 concentrations during pronounced weight loss after bariatric surgery. Thus, significant reduction of visceral fat mass may contribute to the reduced cardiovascular morbidity and mortality after bariatric surgery by a concomitant decrease in PAI-1 concentrations.

Abstract
BACKGROUND Subclinical inflammation in obesity is critical for development of several obesity-associated disorders. We set out to investigate the effect of pronounced weight loss on circulating chemerin levels, a chemoattractant protein that also influences adipose cell function by paracrine and autocrine mechanisms. MATERIAL AND METHODS Thirty-two obese patients undergoing bariatric surgery were tested before and on an average of 18 months after gastric banding or gastric bypass surgery. RESULTS Pronounced weight loss after bariatric surgery was accompanied by improvements in parameters of lipid and glucose metabolism and increased adiponectin levels. Chemoattractant chemerin significantly decreased from 175.91 +/- 24.50 to 145.53 +/- 26.44 ng mL(-1) after bariatric surgery (P < or = 0.01). Concomitantly, hs-CRP as a marker of subclinical inflammation was significantly reduced after weight reduction (P < or = 0.01). CONCLUSIONS We hypothesize that weight-loss induced reduction in circulating chemerin might in conjunction with other factors be associated with diminished recruitment of macrophages in adipose tissue and reduction of subclinical inflammation, which again could partly explain beneficial long-term effects of weight reduction in obese subjects.

Abstract
The objective was to evaluate the utility of urinary 1-hydroxypyrene (1-OHP), S-phenylmercapturic acid (S-PMA), trans,trans-muconic acid (t,t-MA), 3-methyladenine (3-MeAd), 3-ethyladenine (3-EtAd), 8-hydroxy-2'-deoxyguanosine (8-OHdG) and thioethers as biomarkers for assessing the exposure in adult smokers who switched from smoking conventional cigarettes to candidate potential reduced exposure products (PREP) or who stopped smoking. Two electrically heated smoking systems (EHCSS) were used as prototype cigarettes that have significant reductions in a number of mainstream smoke constituents as measured by smoking machines relative to those from conventional cigarettes. Urine samples were collected from a randomized, controlled, forced-switching study in which 110 adult smokers of a conventional cigarette brand (CC1) were randomly assigned to five study groups. The groups included the CC1 smoking group, a lower-tar conventional cigarette (CC2) smoking group, EHCSS1 group, EHCSS2 group and a no smoking group that were monitored for 8 days. Biomarkers were measured at baseline and day 8. The daily excretion levels of these biomarkers were compared among the groups before and after switching, and the relationships between the daily excretion levels of these biomarkers and cigarette smoking-related exposure were investigated using Pearson product-moment correlation and multiple regression analyses. It was concluded that under controlled study conditions: (1) 1-OHP, S-PMA and t,t-MA are useful biomarkers that could differentiate exposure between smoking conventional and EHCSS cigarettes or between smoking conventional cigarettes and no smoking; between S-PMA and t,t-MA, the former appeared to be more sensitive; (2) 3-MeAd could only differentiate between smoking conventional cigarettes and no smoking; the results for 3-EtAd were not conclusive because contradictory results were observed; (3) 8-OHdG had a questionable association with smoking and therefore the utility of this biomarker for smoking-related exposure could not be established; and (4) urinary excretion of thioethers as a biomarker lacked sensitivity to demonstrate a clear dose-response relationship in conventional cigarette smokers, although it could differentiate the excretion levels between those subjects who smoked a conventional cigarette and those who stopped smoking.

Abstract
BACKGROUND Weight loss induced by bariatric surgery is an effective method to reverse obesity and comorbidities. The aim of this prospective weight loss study was to investigate changes of body fat distribution in relation to adiponectin and its isoforms and further to investigate the influence of both body fat distribution and adiponectin on the degree of liver steatosis. DESIGN Fifteen severely obese female patients (body mass index 43.1 +/- 4.1, mean age 34.5 +/- 8.6 years) were examined before and after surgical treatment. Grading of fatty liver disease and the subcutaneous and visceral fat diameters were determined by abdominal ultrasonography. Metabolic parameters were determined using standard methods; serum total adiponectin and its isoforms were detected by enzyme immuno assay (EIA). RESULTS Mean weight loss was 28.3 kg, which was mostly due to a loss in fat mass, accompanied by an increase in total adiponectin and the high molecular weight (HMW) adiponectin isoform. Visceral adipose tissue (VAT) diameter was highly correlated with liver steatosis, even more strongly than the parameters of liver function. In addition, liver steatosis correlated negatively with HMW adiponectin and binary logistic regression revealed that changes in fat mass, HMW adiponectin and alanine aminotransferase (ALT) were the best predictors for changes in the degree of hepatic steatosis. CONCLUSIONS Our results suggest that circulating HMW adiponectin is associated with both VAT and liver steatosis. In summary, the major findings were that the VAT diameter is highly correlated with liver steatosis, even stronger than the parameters of liver function and the association of HMW adiponectin with liver steatosis was better than with total adiponectin.

Abstract
Zusammenfassung
Gegenstand und Ziel: In der vorliegenden Arbeit wurden erstmals Referenzwerte für die Knorpelelastizität und Knorpeldicke am Talus des Pferdes ermittelt. Die postmortal durchgeführte Untersuchung umfasste 24 Pferde verschiedenen Alters (zwei Fohlen, ein Jährling, 21 adulte Tiere). Material und Methoden: Die Knorpelelastizität wurde an 23 Messpunkten mit einer auch intra vitam einsetzbaren Indentermesssonde (Art - scan® 200) getestet. Die Bestimmung der Knorpeldicke erfolgte mit einer Messlupe an 18 Messpunkten des geschnittenen Knorpelpräparats. Ergebnisse: Die Sprunggelenke der neugeborenen Fohlen zeigten eine homogene Verteilung der Knorpelelastizität über den gesamten Rollkamm. Eine Knorpeldickemessung war aufgrund der noch nicht abgeschlossenen enchondralen Ossifikation nicht möglich. Die Tali des Jährlings wiesen bereits eine deutliche Heterogenität der Knorpelelastizität und -dickeF auf. Die adulten Tiere zeigten mit einer hohen Signifikanz (p < 0,001) einen deutlichen Trend einer nach distal abnehmenden Knorpelelastizität und einer gegenläufigen Verteilung der Knorpeldicke. An den proximalen Messpunkten wurden Werte von 0,873–1,321 Newton (N) erreicht, an den distalsten Messpunkten nur noch 0,375–0,550 N. Für die Knorpeldicke ergaben sich proximal Werte von 0,49–0,78 mm und distal von 0,68–1,08 mm. Schlussfolgerung: Die verwendete Messsonde eignet sich zur Bestimmung der Knorpelelastizität beim Pferd. Die Knorpelelastizität und -dicke am equinen Talus weisen ein lokales und altersabhängiges Verteilungs muster auf. Klinische Relevanz: Bei der Detektion von frühen pathologischen Veränderungen der Knorpelmatrix muss die lokalisations- und altersspezifische Ausprägung der Knorpelelastizität berücksichtigt werden.

Abstract
The use of second-generation antipsychotics (SGAs) is associated with metabolic side effects including weight gain, diabetes mellitus and an atherogenic lipid profile. These adverse effects are not only the risk factors for cardiovascular disease, insulin resistance and diabetes mellitus leading to increased morbidity and mortality but may also impair the patient's adherence to treatment. SGAs in particular are associated with significant weight gain with clozapine and olanzapine carrying the highest risk, whereas newer agents, such as risperidone and aripiprazole, are considered to be less prone to cause weight gain. Consequently, a consensus development conference convened issuing recommendations on patient monitoring when treated with SGAs. The metabolic effects of antipsychotic drugs should be of concern when planning a patient's treatment strategy. Baseline screening and regular follow-up monitoring whose intervals should depend on the individual predisposition are advised. Possible therapeutical strategies for the management of drug-induced obesity include therapeutic approaches, such as life style change and pharmaceutical intervention. Drugs with a weight reducing effect become more important because of the lack of compliance with behavioural intervention. Topiramate, histamine-antagonists, dopaminergic- and serotoninergic agents have shown positive results in the management of psychotropic medication induced weight gain. However, further trials are required to support a specific therapeutical approach as well as studies to investigate the underlying mechanisms for future drug development.

Abstract
Relationship education programs such as Ehevorbereitung--Ein Partnerschaftliches Lernprogramm (Premarital Preparation--A Couples' Learning Program) and the Relationship Education and Relationship Enhancement Program (PREP) can help prevent marital distress among newlyweds. Thus, it is important to understand which couples respond best to the intervention and which couples respond less well. E. A. Schilling, D. H. Baucom, C. K. Burnett, E. A. Allen, and L. Ragland (2003) unexpectedly found that the more women increased positive communication in response to PREP, the more likely they were to become distressed in the subsequent 5 years. The current study explores similar issues, investigating a relationship education program in Germany. The current results indicate that couples are susceptible to future relationship distress if women demonstrate extreme increases in positive and decreases in negative communication after intervention. Implications are provided for adapting these relationship education programs in the future.

Abstract
Second-generation antipsychotic agents (SGAs) are increasingly replacing first-generation antipsychotic agents due to their superior activity against the negative symptoms of schizophrenia, decreased extrapyramidal symptoms and better tolerability. However, some SGAs are associated with adverse metabolic effects as significant weight gain, lipid disorders and diabetes mellitus. The pathogenesis of SGA-induced disturbances of glucose homeostasis is unclear. In vivo studies suggest a direct influence of SGAs on peripheral insulin resistance. To this end, we analyzed whether olanzapine might alter glycogen synthesis and the insulin-signaling cascade in L6 myotubes. Glycogen content was diminished in a dose- and time-dependent manner. Within the insulin-signaling cascade IRS-1 tyrosine phosphorylation was induced several fold by insulin and was diminished by preincubation with olanzapine. IRS-1-associated PI3K activity was stimulated by insulin three-fold in L6 myotubes. Olanzapine inhibited insulin-stimulated IRS-1-associated PI3K activity in a dose-dependent manner. Protein mass of AKT, GSK-3 and GS was unaltered, whereas phosphorylation of AKT and GSK-3 was diminished, and pGS was increased. Finally, we compared olanzapine with amisulpride, an SGA clinically not associated with the induction of diabetes mellitus. Glycogen content was diminished in olanzapine-preincubated L6 cells, whereas this effect was not observed under the amisulpride conditions. We conclude that olanzapine impairs glycogen synthesis via inhibition of the classical insulin-signaling cascade and that this inhibitory effect may lead to the induction of insulin resistance in olanzapine-treated patients.

Abstract
AIMS/HYPOTHESIS Elevated fasting and postprandial plasma levels of triglyceride-rich lipoproteins (TGRLs), i.e. VLDL/remnants and chylomicrons/remnants, are a characteristic feature of insulin resistance and are considered a consequence of this state. The aim of this study was to investigate whether intact TGRL particles are capable of inducing insulin resistance. METHODS We studied the effect of highly purified TGRLs on glycogen synthesis, glycogen synthase activity, glucose uptake, insulin signalling and intramyocellular lipid (IMCL) content using fully differentiated L6 skeletal muscle cells. RESULTS Incubation with TGRLs diminished insulin-stimulated glycogen synthesis, glycogen synthase activity, glucose uptake and insulin-stimulated phosphorylation of Akt and glycogen synthase kinase 3. Insulin-stimulated tyrosine phosphorylation of IRS-1, and IRS-1- and IRS-2-associated phosphatidylinositol 3-kinase (PI3K) activity were not impaired by TGRLs, suggesting that these steps were not involved in the lipoprotein-induced effects on glucose metabolism. The overall observed effects were time- and dose-dependent and paralleled IMCL accumulation. NEFA concentration in the incubation media did not increase in the presence of TGRLs indicating that the effects observed were solely due to intact lipoprotein particles. Moreover, co-incubation of TGRLs with orlistat, a potent active-site inhibitor of various lipases, did not alter TGRL-induced effects, whereas co-incubation with receptor-associated protein (RAP), which inhibits interaction of TGRL particles with members of the LDL receptor family, reversed the TGRL-induced effects on glycogen synthesis and insulin signalling. CONCLUSIONS/INTERPRETATION Our data suggest that the accumulation of TGRLs in the blood stream of insulin-resistant patients may not only be a consequence of insulin resistance but could also be a cause for it.

Abstract
The pharmacokinetics of in vitro metabolism of the tobacco-specific nitrosamine, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK; concentration range 0.03-250 microM) and its proximal metabolite, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL; 0.04-250 microM), were determined in Syrian golden hamster liver, lung, and kidney tissue slices in organ culture under identical experimental conditions. In the lung, a target organ for NNK animal carcinogenesis, total NNK metabolism was relatively low (maximum 23%) and oxidative metabolism by alpha-hydroxylation to DNA-reactive intermediates accounted for 13-31% of metabolism. The liver, a non-target organ for NNK carcinogenesis, showed the highest capacity to metabolise NNK (total metabolism 80%), and alpha-hydroxylation accounted for 12-25% of metabolism. The kidney, another non-target organ, also showed a low capacity for NNK metabolism (maximum 32%) and alpha-hydroxylation accounted for <3% of metabolism. Detoxification of NNK by pyridyl N-oxidation was similar in lung (5-22%) and liver (5-23%), and negligible in kidney (<2%), while carbonyl reduction of NNK to NNAL was greatest in the kidney (95-100%), followed by liver (59-79%) and lung (47-81%). NNAL is devoid of biological activity in the hamster and total metabolism was about tenfold lower than that of NNK in all tissues (<13% liver; <4% lung and kidney). In the liver, alpha-hydroxylation was the predominant pathway of NNAL metabolism at almost all concentrations (31-68% of total metabolism), whereas N-oxidation prevailed in the kidney (47-68%). In the lung, a concentration dependent decrease in the relative amount of alpha-hydroxylation (23-72%) with increasing NNAL concentrations occurred at the expense of N-oxidation (25-72%). Little or no metabolism of NNAL back to NNK was evident in any tissue.

Abstract
Zusammenfassung. In diesem Projekt wurde zum ersten Mal im deutschsprachigen Raum ein Ehevorbereitungsprogramm (EPL = Ein Partnerschaftliches Lernprogramm) mittels einer quasiexperimentellen Langzeitstudie mit multimethodaler Diagnostik auf seine kurz- und langfristige Effektivität empirisch überprüft. An der Prä-Messung nahmen in der EPL-Gruppe N = 64 Paare teil, in der Kontrollgruppe N = 32 Paare. Nach 5 Jahren konnten N = 44 EPL- und N = 13 Kontrollpaare nachuntersucht werden. Die Ergebnisse zeigen, daß die EPL-Paare dauerhaftere Lerneffekte in Form von konstruktiverer Kommunikation aufweisen, die sich in einer stabileren Ehezufriedenheit und in wesentlich geringeren Trennungs- und Scheidungsraten im Vergleich zu den Paaren der Kontrollgruppe niederschlagen.

Abstract
Autophosphorylation of insulin receptors from human placental membranes prepared with iodoacetamide was more than double that of control receptors prepared without iodoacetamide. Dithiothreitol (DTT) treatment of control receptors prepared without iodoacetamide resulted in increased autophosphorylation. However, DTT was without effect on insulin receptors prepared with iodoacetamide. Phosphopeptide analysis showed that while 32P-labeling of all of the phosphopeptides was increased in insulin receptors from membranes prepared with iodoacetamide, two additional phosphopeptides were detected and identified as deriving from the juxtamembrane domain, containing tyrosine residue 960. Similar results were produced by DTT treatment of control insulin receptors. These observations suggest that a thiol(s) may be involved in insulin receptor autophosphorylation in the juxtamembrane domain.

Abstract
A 51-year-old male patient with no history of musculo-skeletal or myopathic abnormalities, but suffering from manic-depressive psychosis, attempted suicide with an overdose of dolpersin hydrochloride (Mydocalm), dipenzepine hydrochloride (Noveril), meprobamate (Mepronox) and nitrazepam (Mogadon). He developed high fever, muscle rigidity, tachycardia, arrhythmias, hypotension and mottled cyanosis, symptoms well-known in persons with malignant hyperthermia, an autosomally inherited disease of skeletal muscle. There is also discussed the manifestation and the symptoms of an acute rhabdomyolysis. The diagnosis was confirmed by chemical pathological laboratory findings, including respiratory and metabolic acidosis, myoglobinaemia accompanied by myoglobin diuresis, and elevated creatine phosphokinase (CPK values up to 2790 U/l). Electron microscopic examination of muscle tissue revealed signs of myolysis and mitochondrial reactions with pleoconic hyperplasia. No inhalation anaesthetics or skeletal muscle relaxants, such as succinyl choline, were used in this case. Therefore, malignant hyperthermia might have been induced by a combination of drugs which were not known to induce this abnormal muscular reaction. However, the muscle relaxant effect of dolpersin hydrochloride may have acted as a possible inducer of the attack.
