Current surgical management in RET mutation carriers [Aktualne postępowanie chirurgiczne u nosicieli mutacji proto-onkogenu RET].

Medullary thyroid carcinoma (MTC) still remains a rare endocrine tumor. 20-25% of MTC cases are genetically determined. The detection of the RET proto-oncogene mutation in 1993 allowed to understand the unique genotype-phenotype relationships in hereditary medullary thyroid carcinoma (HMTC) and formed the basis for therapeutic decisions based on the molecular results.

Efficient synthesis of triarylamine-based dyes for p-type dye-sensitized solar cells.

The class of triarylamine-based dyes has proven great potential as efficient light absorbers in inverse (p-type) dye sensitized solar cells (DSSCs). However, detailed investigation and further improvement of p-type DSSCs is strongly hindered by the fact that available synthesis routes of triarylamine-based dyes are inefficient and particularly demanding with regard to time and costs. Here, we report on an efficient synthesis strategy for triarylamine-based dyes for p-type DSSCs.

Effect of constant magnetic field on anaerobic digestion of algal biomass.

The aim of the study was to determine the impact of the constant magnetic field (CMF) application on the effectiveness of anaerobic digestion of algal biomass. The highest yield of biogas in the range of 448.9 L/kg volatile solids (VS) to 456.

On the Size Effect of Gelation Kinetics in RF Aerogels.

We experimentally and theoretically investigate the size effect of gelation using Resorcinol-Formaldehyde aerogels. We find a clear dependence of gelation time on the sample size under mild shear conditions. We developed a theoretical model based on Smoluchowski's aggregation model adding, however, a growth term which accounts for the continuous growth of the colloidal particles while clustering happens.

[Study of depressiveness with Beck Depression Inventory in patients with cardiac arrhythmias].

Introduction: Atrial fibrillation belongs to the group of supraventricular arrhythmias. The episode begins with anxiety about the loss of health or life. Anxiety is accompanied by depressive disorders.

[Measurement of anxiety with C.D. Spielberger's test in patients with cardiac arrhythmias].

Introduction: Atrial fibrillation is a common supraventrical arrhythmia. The onset of fibrillation is marked by fear of loss of health or life. Symptoms of depression occur concurrently.

[Gastroesophageal reflux disease among patients suffering from coronary artery disease].

Introduction: In recent years, the increasing frequency of gastroesophageal reflux disease (GERD) occurrence has been observed. Gastroesophageal reflux disease may take the form of so called 'heart mask' (i.e.

[A search for psychobiological determinants of anxiety disorders].

Unlabelled: The aim of the study was to search for measurable, objective, and reproducible biological factors such as gene polymorphisms that increase the risk of an anxiety disorder, distinguishing personality traits predisposing to the anxiety disorder. The material comprised 103 patients fulfilling criteria of an anxiety disorder (panic disorders, generalized anxiety disorders, phobic disorders) and a control group of 100 subjects matched for age and free of neuropsychiaric disease.

Methods: The genes studied were: COMT (catechol-oxygen-methyltransferase), MAO-A (monoamine oxidase A), and 5-HTT-LPR (serotonine transporter).

[Personality profile of patients with anxiety disorder, as studied with the 16PF Cattell's questionnaire and Cloninger's TCI].

Unlabelled: The aim of the present study is a characterisation of the personality dimensions of patients with anxiety disorder.

Method: Personality of 103 patients with different mixed ICD-10 diagnosis of anxiety disorders (79 females, 24 males, mean age: 38 +/- 12 years) were studied and compared to 183 healthy controls (117 females, 66 males, mean age: 35 +/- 14) using the 16 PF Cattell's Questionnaire and Cloninger's TCI. Spielberger's State and Trait Anxiety Inventory and Self-evaluation of the Beck's Depression Scale were also applies.

Association studies of MAO-A, COMT, and 5-HTT genes polymorphisms in patients with anxiety disorders of the phobic spectrum.

Recent studies provide evidence that anxiety disorders may be linked to malfunction of serotonin neurotransmission or impaired activity of enzymes metabolising the catecholamines. Functional polymorphisms in the MAO-A uVNTR promoter gene, the COMT gene (Val158Met) exon 4, and the 5-HTT promoter gene (44 bp ins/del) were investigated in 101 patients with phobic disorders of the anxiety spectrum and 202 controls matched to the patients for sex, age and ethnicity. There were no significant differences between controls and patients in the allele and genotype frequencies of the 5-HTT and COMT gene polymorphisms.
