Abstract
Although earlier research has shown that individual differences on the spectrum of attention deficit hyperactivity disorder (ADHD) are highly heritable, emerging evidence suggests that symptoms are associated with complex interactions between genes and environmental influences. This study investigated whether a genetic predisposition [Note that the term 'genetic predisposition' was used in this manuscript to refer to an estimate based on twin modeling (an individual's score on the latent trait that resembles additive genetic influences) in the particular population being examined.] for the symptom dimensions hyperactivity and inattention determines the extent to which unique-environmental influences explain variability in these symptoms. To this purpose, we analysed a sample drawn from the Twins Early Development Study (TEDS) that consisted of item-level scores of 2168 16-year-old twin pairs who completed both the Strengths and Difficulties Questionnaire (SDQ; Goodman, in J Child Psychol Psychiatry 38:581-586, 1997) and the Strength and Weaknesses of ADHD Symptoms and Normal Behavior (SWAN; Swanson, in Paper presented at the meeting of the American Psychological Association, Los Angeles, 1981) questionnaire. To maximize the psychometric information to measure ADHD symptoms, psychometric analyses were performed to investigate whether the items from the two questionnaires could be combined to form two longer subscales. In the estimation of genotype-environment interaction, we corrected for error variance heterogeneity in the measurement of ADHD symptoms through the application of item response theory (IRT) measurement models. A positive interaction was found for both hyperactivity (e.g., [Formula: see text] = 2.20 with 95% highest posterior density interval equal to [1.79;2.65] and effect size equal to 3.00) and inattention (e.g., [Formula: see text] = 2.16 with 95% highest posterior density interval equal to [1.56;2.79] and effect size equal to 3.07). These results indicate that unique-environmental influences were more important in creating individual differences in both hyperactivity and inattention for twins with a genetic predisposition for these symptoms than for twins without such a predisposition.

Abstract
Research suggests that people attribute more negative traits to individuals with obesity than to non-obese individuals, and that females with obesity are seen more negatively than males. The theory also suggests that stereotypes are cognitive predecessors of prejudices. The aims of this research were to examine the latent structure underlying anti-fat stereotypical traits, differences in perceiving individuals with obesity and non-obese individuals, male and female individuals with obesity, as well as the role of anti-fat stereotypes in anti-fat prejudices. The sample consisted of 106 respondents (Male = 16; Female = 86; Mean age = 19.98), who graded stimuli photographs of male and female individuals (with obesity and average-weight) on series of anti-fat stereotypical traits on two occasions, and filled in Anti-fat prejudices questionnaire. The data were analyzed through EFA and CFA, ANOVA, and structural equation modeling (moderation). Four factors behind stereotypical traits were extracted: Positive social image, Perceived lack of self-care, Perceived persistence, and Antipathy. It has been shown that respondents gave stimuli photographs of individuals with obesity lower scores on Positive social image and Perceived persistence, and higher scores on Perceived lack of self-care and Antipathy. The same results were obtained for females within the subsample of individuals with obesity. Furthermore, it has been shown that certain anti-fat stereotypes (Positive social image, Perceived lack of self-care, and Perceived persistence) predict anti-fat prejudices, and that gender was a significant moderator of the effect of Perceived lack of self-care on anti-fat prejudices. We can conclude that individuals with obesity are indeed seen in a more negative light than non-obese individuals, and that this is more pronounced for females with obesity, which is in accordance with previous studies. Moreover, the results suggest the possible role of anti-fat stereotypes as cognitive predecessors of anti-fat prejudices, and that gender of individuals with obesity has an effect on this relationship.

Abstract
The aim of this study was to evaluate KCNQ1 K+ channel expression in the frog kidney of Rana esculenta. KCNQ1 K+ channel, also known as KvLQT1, is the pore forming α-subunit of the IKs K+ channel, a delayed rectifier voltage-gated K+ channel, which has an important role in water and salt transport in the kidney and gastrointestinal tract. The expression of KCNQ1 K+ channel along tubular epithelium differs from species to species. In the present study the expression of KCNQ1 K+ channel in the frog kidney has been demonstrated by immunohistochemistry. The presence of KCNQ1 K+ channel was demonstrated in the epithelial cells of distal convoluted tubule and collecting duct. However, the pattern of expression of KCNQ1 K+ channel differs between distal convoluted tubules and collecting duct. All epithelial cells of distal convoluted tubules revealed basolateral expression of KCNQ1 K+ channel. On the contrary, only the single cells of collecting duct, probably intercalated cells, showed diffuse cell surface staining with antibodies against KCNQ1 K+ channel. These findings suggest that KCNQ1 K+ channel has cell-specific roles in renal potassium ion transport.

Abstract
Quadricuspid aortic valve is rare congenital anomaly. There are only 197 cases published in literature so far. That includes clinical and autopsy reports. This congenital anomaly occurs more often in pulmonary valve but function stays normal in 10 of lies. On the other side, in aortic position valve is malfunctioning in 50% of cases. Valve regurgitation is more likely to occur than stenosis In this kind of malformation, valves are prone to early dysfunction and endocarditis due to different valve architecture and unequal distribution of mechanical stress along valve cusps. Aortic valve replacement is indicated in younger population of these patients. This is a case report of rare congenital anomaly of big blood vessels--aortic valve with four cusps. This anomaly produced significant aortic regurgitation so this patient was indicated for aortic valve replacement.

Abstract
Autoimmune diseases of the thyroid gland (ADTG) which include, Graves' disease, Hashimoto thyroiditis, primary hypothyroidism with atrophic thyroiditis, postpartum thyroiditis and 'silent' thyroiditis, are characterized by the presence of serum thyroid autoantibodies (TAB). Thyroid autoantibodies are not rare even in the general population of all ages, and their presence in women is 5 times more than in men. The aim of our study was to define the prevalence of thyroid autoantibodies in patients on chronic treatment by amiodarone (AMD), an antiarrhythmic drug rich in iodine, with a potential cytotoxic effect. We have used a section study during a period of two years. Ninety six consecutive patients under AMD treatment were studied, 55 men and 41 women (mean age 62.2 years, range 26-82 years) who referred to us to study their thyroid function. Our results showed that antithyroid antibodies in patients under AMD treatment, with or without thyroid dysfunction, were in similar concentrations as in the general population. A statistically significant greater frequency of increased thyroid peroxidase antibodies (TPOAb) was present in female patients under AMD treatment. When AMD treatment lasted longer than 24 months, the TPOAb were statically higher as compared to those patients under AMD treatment for less than 24 months.

Abstract
Adequate open exposure of the mitral valve is necessary to accomplish reconstruction or replacement of the diseased mitral valve apparatus. The technique employed by most cardiac surgeons for mitral valve access involves median sternotomy and vertical left atriotomy posterior to the interatrial sulcus. However, certain conditions can somethimes make this approach very difficult. Different approaches are discussed with particular emphasis on our case in which the transaortic double valve replacement have been performed.

Abstract
Coronary artery bypass surgery in patient with bad left ventricular function is a challenge for surgical time. Specially important is monitoring of haemodynamics. We performed this open, prospective, randomized study with the aim to assess haemodynamics and oxygen profile monitoring. 34 pts for coronary surgery (EF < 40%) were divided in two groups. Group A, 17 pts. Received glucose-insulin-potassium (GIK) solution. Group B, 127 pts. Received Ringer solution. Haemodynamic and oxygen metabolism parameters were measured in four time points. I after the induction in anesthesia; II after the operation; III 6 hours post op.; IV 24 hour post op. Data are expressed as mean +/- SD, Anova for repeated measures followed by Newman-Keuls testing were used. In both groups were evident deterioration of cardiac function during first 6 h as well as VO2 and DO2, more prominent in Group B. Significant recovery and improvement of cardiac function were evident in Group A after 24 h. CI during the time in Group A improves significantly (2.14 +/- 0.36 v. 3.05 +/- 0.55; p = 0.0002) and difference during the time between groups was p = 0.005. LVSWI improved significantly during the time him Group A (AIII vs. AIV) p = 0.007. Simultaneously. VO2 improves significantly in Group A (103 +/- 21 vs. 164 +/- 30, p = 0.00001) while difference between groups in DO was p = 0.037. Importance of oxygen metabolism monitoring for both, left ventricular function and haemodynamics assessment was evident in our study.

Abstract
It has been 45 years ago when Longmire (1958.) used internal thoracic artery (ITA) for the first time in coronary artery bypass surgery (CABG). In this review, we are presenting novel surgical approaches in CABG surgery. We have also been summarized the best of knowledge, up to date, regarding histology, pharmacology and pathophysiology of conduits (VSM, ITA and alternative venous and arterial grafts) which have been used in CABG surgery, as well as factors influence on its short and long-term patency.

Abstract
The concept of artificial circulatory support has been established almost 200 years ago. It has only been within the last four decades that physicians and engineers have developed mechanical assist devices that can temporarily support the circulation until the native heart recovers from a reversible injury. If the heart does not recover sufficient function to maintain adequate hemodynamics, long-term circulatory support or permanent replace (biologically--heart transplant or permanent mechanical circulatory support) is needed. In this paper we describe the devices (intraaortic balloon pump, roller, centrifugal and axial pumps), that are in current clinical use for temporary (short-term) mechanical circulatory support.

Abstract
The incidence of redo myocardial revascularization is increasing lately. These procedures are accompanied by the higher operative risk, and the use of internal thoracic artery graft may have additional negative impact on early-rization. Mortality and morbidity in this group did not differ significantly compared to a group where only venous grafts were used. Independent predictors of the unfavorable outcome (for both groups) were the presence of the chronic pulmonary disease, age over 65 and NYHA functional class IV. In the group with internal thoracic graft it was the age over 65, while in the group with only vein grafts it was chronic pulmonary disease. We have discussed potential problems during the redo procedure in patients in whom internal thoracic graft was used during the first procedure.

Abstract
Heavily calcified ascending aorta predisposes to aortic injury and distal embolization during total or partial cross-clamping, during the performance of open-heart procedures. Placement of the arterial cannula may be particularly difficult, occasionally virtually impossible using the standard technique, while placing the clamp on such aorta may be extremely risky. We present a case where we have used a Foley-balloon catheter to occlude the densely calcified ascending aorta, during a aorta-coronary bypass procedure, thus completely avoiding the use of the total aortic clamp.

Abstract
Inability to wean a patient from the cardiopulmonary bypass after open heart procedure is reality of the clinical practice. The only realistic chance for these patients is some form of mechanical circulatory support. Over the period from November 1988 to November 1993, in 17 patients the roller-pump mechanical assist device was inserted, i.e. 0.47% of 3589 patients were operated on during this period. Thirteen patients required mechanical circulatory support immediately after surgical procedure due to inability to wean them from cardiopulmonary bypass. In three patients the roller-pump was inserted preoperatively (percutaneous insertion), and in one patient mechanical circulatory support was started six hours after the procedure for sudden cardiac deterioration. Partial and temporary "bypass" of the damaged left ventricular function is achieved by insertion of inflow cannula into the left atrium, and outflow cannula into the ascending aorta. Depending on the inflow cannula size and volume load, we were able to achieve blood flow of 3.5 to 5 liters/minute. Using this system we were able to improve the left ventricular function in eight patients (47%), and five patients were discharged from hospital (29.4%). The roller-pump mechanical circulatory support proved to be efficient, reliable, easy to monitor and operate. Overall results are comparable to the published data as well as to other types of more versatile and costly devices for mechanical circulatory support.
